Abstract (en)
[origin: EP2045761A1] It is possible to linearly arrange cells and indicate particular data in the order of colors of respective sells. A code system uses an optical symbol decoding method capable of reading the color arrangement if the arrangement continuity and the linear shape are maintained. The data expression method may be other than 'the order of colors'. For example, it is possible to employ a method for allocating a numeric value to each of the colors by one-to-one correspondence (R - 0, B = 1, etc.), a method for allocating data by a color transition ('CM' = 'MY' = 'YC' = 0, 'CY' = 'YM' = 'MC' = 1, etc.), a method for allocating data for a combination of colors, and the like.
